This video of Saturn's second largest moon, Rhea, shows the western half of its second largest impact basin, Tirawa. This ancient impact basin is 370 kilometers across and roughly 6 kilometers deep. The broad arcuate scarp cutting across scene center is the battered rim of Tirawa. The floor of Tirawa, at right, is heavily cratered, indicating it formed in ancient times when a 30-40 kilometer wide comet struck Rhea. The two large craters just beyond the rim are 55 and 60 kilometers across. This video was created using stereo topography generated by Dr. Paul Schenk of the Lunar and Planetary Institute in Houston Texas from Cassini imaging data returned in 2008. Although enhanced, the color in this view is an approximation of what we might actually see.

The video begins south of Tirawa and flies north before reversing course for a close pass over the western rim of the basin and the two smaller craters just beyond.
